Description

Die Erfindung betrifft eine Einrichtung zum Abisolieren eines mehradrigen Kabels, wobei eine Transporteinheit zum Transport des Kabels in kabelachsialer Richtung, ein Messer zur Abmantelung des Kabels und ein weiteres Messer zur Abisolierung der entdrillten Kabeladern vorgesehen ist, wobei ein Separator vorgesehen ist, der mit quer zur Kabelachsrichtung wirkenden Bewegungen bzw. Kräften die Kabeladern entdrillt und parallel orientiert. Desweiteren betrifft die Erfindung ein Verfahren nach dem Oberbegriff des Anspruchs 4.The invention relates to a device for stripping a multicore cable, wherein a transport unit for Transport of the cable in cable axial direction, a knife for stripping the cable and another knife for Stripping the untwisted cable wires is provided wherein a separator is provided which transversely to Kabelachsrichtung acting movements or forces the Cable cores untwisted and oriented in parallel. Furthermore, concerns the invention a method according to the preamble of claim 4.

Aus der Schrift WO99/52188 ist eine Abisoliervorrichtung für mehradrige Kabel bekannt geworden. Die Kabeladern werden mechanisch durch eine streifende Bewegung entdrillt und parallel zueinander orientiert, bevor die Kabeladern mittels eines Mehrfachmessers abisoliert werden. Die streifende Bewegung und die parallele Orientierung wird mittels federbeaufschlagbaren, einander gegenüberliegenden Backen erreicht, wobei die Backen als gefederte Gleitstücke wirken. Die Kabeladern führen gegenüber den Gleitstücken eine Relativbewegung aus, wobei die verdrillten Kabeladern vor dem Abisolieren separiert und parallel orientiert werden.The document WO99 / 52188 discloses a stripping device become known for multi-core cable. The cable wires are mechanically untwisted by a grazing motion and oriented parallel to each other before the cable wires be stripped by means of a multiple blade. The grazing motion and the parallel orientation becomes by means of spring-loaded, opposite one another Baking is achieved, with the jaws as sprung sliders Act. The cable cores lead opposite the sliders a relative movement, wherein the twisted cable wires separated before stripping and oriented in parallel become.

Ein Nachteil der bekannten Einrichtung liegt darin, dass durch die streifende Bewegung Kräfte in Kabelachsrichtung auf die Isolation der Kabeladern wirken, welche Kräfte die Isolation leicht dehnen. Nach dem Abisolieren kann sich die Isolation wieder zusammenziehen, was zu grosse, materialabhängige Abisolierlängen zur Folge hat. A disadvantage of the known device is that by the grazing motion forces in Kabelachsrichtung on the insulation of the cable cores act, which forces the Stretch insulation slightly. After stripping, the Tightening up the isolation, which is too big, material-dependent stripping lengths result.

Aus der Schrift FR 2 167 417 ist ein Separator bekannt geworden, der quer zur Kabelachsrichtung wirkende Bewegungen zum Entdrillen und parallel Orientieren von Kabeladern ausführt. Zwei entlang einer Schräge bewegliche Platten, die auf die zu entdrillenden Kabeladern mit einer gegenläufigen Bewegung einwirken, sind in Querrichtung federbeaufschlagt.From document FR 2 167 417 a separator is known become, which acts transversely to the cable axis direction Movements for untwisting and parallel orientation of Cable cores executes. Two moving along a slope Plates on the cable cores to be untwisted with a counteracting movement are in the transverse direction spring-loaded.

Nachteilig bei dieser Einrichtung ist, dass die Isolation der Kabeladern in Kabelachsrichtung fest eingespannt ist und sich der Isolationsanschnitt nach dem Abisolieren verschieben kann.The disadvantage of this device is that the insulation the cable cores is firmly clamped in Kabelachsrichtung and the insulation gate after stripping can move.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 oder 4 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Einrichtung zu schaffen, mittels der Kabeladern eines Kabels problemlos entdrillbar und orientierbar sind.The invention aims to remedy this situation. The invention, as characterized in claim 1 or 4 solves the problem, to avoid the disadvantages of the known device and to create a device by means of the cable wires of a Cables are easily undressed and orientable.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die elastische Isolation beim Entdrillen der Kabeladern nicht gedehnt wird. Die Abisolierlänge der Kabeladern verändert sich nach dem Entdrillen nicht. Die beim Abisolieren vorgegebene Abisolierlänge der Kabeladern bleibt erhalten. Ausserdem sind kürzere Abmantellängen realisierbar, weil die Isolation nicht gedehnt wird.The advantages achieved by the invention are in essential to see that the elastic insulation when untwisting the cable wires is not stretched. The Stripping length of the cable wires changes after the Do not untangle. The predetermined during stripping Stripping length of the cable wires is retained. Moreover shorter sheath lengths are feasible, because the Isolation is not stretched.
